Abstract: An apparatus for cooling an electronic device is disclosed. In an aspect, the apparatus includes a vapor chamber coupled to a heat generating component of the electronic device. In an aspect, the vapor chamber is coupled to an inner surface of an outer cover of the electronic device and conforms to a shape of the inner surface of the outer cover. In another aspect, the vapor chamber forms the outer cover of the electronic device. The vapor chamber comprises a sealed container, a wick structure disposed on an inner surface of the sealed container, and a fluid contained in the sealed container, wherein as heat is applied to an evaporator side of the sealed container coupled to the heat generating component, the fluid vaporizes over a condenser side of the sealed container opposite the evaporator side and returns to the evaporator side via the wick structure.

Abstract: An electronic device includes a housing with a plurality of sides and electronics components in the housing. A porous and thermally conductive material is associated with the housing. The material has a thermal conductively (k), and a porosity between 10% and 70% that results in a specific heat (ρ) and density (Cp) for the material, such that k*ρ*Cp is between 0 (J*W)/(m4*K2) and 1,000,000 (J*W)/(m4*K2). The material may be: a glass-based material having a thermal conductivity between 0.5-2 W/m-K, a density between 1000-2500 kg/m3, and a specific heat between 500-1000 J/kg-K; a metal-based material having a thermal conductivity between 300-400 W/m-K, a density between 4000-8000 kg/m3, and a specific heat between 200-300 J/kg-K; and a plastic-based material having a thermal conductivity may be between 0.1-0.4 W/m-K, a density between 400-1000 kg/m3, and a specific heat between 1900-2000 J/kg-K.

Abstract: An innovative passive cooling solution with sealed UAV enclosure system allows heat from a semiconductor chip to be dissipated to the ambient environment through evaporation/condensation phase-change cooling and air cooling a heat sink such as a fin without any additional power consumption to operate cooling solution. One example of such a solution may include a pipe with a fin and a fluid. The pipe may include a wick structure along an inner surface of the pipe configured to allow the fluid to travel within the wick structure and to allow a vapor form of the fluid to exit the wick structure towards a center of the pipe.

Abstract: Some features pertain to a quad-rotor or other aerial drone having a thermoelectric generator (TEG) for harvesting waste heat from a processor of the drone. The TEG is positioned, in some examples, with its inner metal electrode coating adjacent the drone processor to function as the “hot” side of the TEG. The outer metal electrode coating of the TEG forms a portion of the outer surface of the housing of the drone to function as the “cold” side of the TEG. The inner and outer metal coatings of the TEG are coupled to a battery recharger so current generated by the TEG during operation of the drone can help recharge the drone battery to extend flight time. In some examples, an outer perimeter of the TEG extends into an airflow region near the drone rotors so propeller wash serves to cool the perimeter of the TEG.

Abstract: An active heat transfer device is proposed for heat management in apparatuses such as mobile devices. The proposed heat transfer device may include a thermoelectric (TE) layer, and first and second electrodes both on lateral surfaces of the TE layer. When there is a voltage differential between the first and second electrodes, heat from a heat source may be transferred laterally within the TE layer from the first electrode to the second electrode.
